TARGET?R.`= "TICE APPARATUS.

To all whom it may concern:

Be it known that l, JAMES M. CLARK, 3rd, a citizen of the United States,residing at Providence, in the county of Providence and State of Rhodeisland, have invented a certain new and useful Improvement inTarget-Practice Apparatus, of which the following is a specification,reference being had therein to the accompanying drawings.

The invention relates to an improvement in target practice apparatus forsmall firearms.

The object of the invention is to provide a practice apparatus in whicha permanent or self-recording record may be made of any wabbling orvibrating` movement of the muzzle of the gun during the aiming so thatthe instructor and the pupil can both by study of the record observe theunsteadiness of the hand or the various movements of the muzzle of thegun in aiming, also an improved target and holder, and an improvedmechanism for actuating the needle.

In carrying out this invention there is provided a target and a lire armequi ped with mechanism which can be operated by a trigger as in anordinary fire arm, the mechanism which is actuated by the firingmechanism of the fire arm including a pointed needle which has a limitedrange of movement and which is adapted to pierce the target when drivenforward and is provided with recoil mechanism which draws the needleback into the barrel of the gun after the firing, the target being soconstructed that it is adapted to be maintained in contact with the endof the barrel of the fire arm during the entire aiming the barrel beingequipped with a recording instrument which will record upon the targetthe lateral or vibratory movements of the muzzle of the barrel while itis pressed against the target.

The invention will be fully understood from the following descriptiontaken in connection with the accompanying drawings, and the novelfeatures are pointed out and clearly delined in the claims at the closeof the specification.

Fig. Gis an end view and Fig. 7 is a side view of the target and holder. Fig.8 is an enlarged vertical sectional view through the target block orholder, partly broken away, showing the means for severing the used uptarget from the strip. Fig. 9 is a view of a portion of a target strip.

rllhe apparatus is adapted to be used with a rifle of any ordinarybreech-loading type..

In the drawings l represents the stock and 2 the barrel of a rifle ofordinary construction having a firing bolt 3 and firing pin 4, aforesight 5 and rearsight G. The gun may be equipped with mechanism ofwell known construction controlled by a trigger 7 to actuate the firingbolt. Fit-ting loosely within the barrel of the gun so as to loeslidable therein is a spring S, preferably made of flat steel wire woundclose and terminating at its forward end in a needle 9 central with theaxis of the barrel and preferably made integral with the spring. lViththe normal adjustment of the parts the needle will eX- tend nearly tothe front end of the barrel, but preferably about an eighth of an inchback of the muzzle. The spring S is of somewhat less length than thebarrel, the rear end of the spring being connected with a rod 10 to therear end of which is secured a piston head or movable plug 11. The meansshown for connecting the rod 10 with the spring 8 is to form the rearend of the spring with a hook 19 and to form the forward end of the rod10 with an eye or loop 20 with which the hook 19 engages. The purpose ofmaking the connection in this way is to permit the spring S to bedetached from the rod 10 for convenience in assembling and removing theparts. A tube 12, which is partly within the chamber 13 of the gun andextends for some distance into the barrel, has a sliding fit within thebarrel and is formed with a ring 14e around its periphery which isadapted to bear against the shoulder 15 at the inner end of thecartridge chamber to limit the forward movement of the tube 12. Theblock 11, to which the rear end of the rod 10 is fastened, has a slidingfit within the tube 12, said tube 12 being crimped over at its rear endto prevent the plug from being pushed rearwardly out of the tube.nclosed within the tube is a spiral spring 16 which surrounds the rod10, the rear end of the said spring being fast to or abutting againstthe inner end of the plug 11, and the forward end of the spring 16abutting against the crimped inner end 17 of the tube 12. The spring 16is preferably lighter and more open than the spring 8. Vhen the triggeris pulled and the hammer strikes the firing bolt 3, the bolt is drivenforward until the pin strikes the plug 11, the force of which isimparted to the small rod 10 driving it forward a short distance andthereby forcing the spring 8 forward sutliciently to cause the needle 9to protrude from the barrel a suflicient distance to puncture the target18 if the target 18 is in contact with the muzzle end of the barrel. Notonly will the spring 8 be driven forward a distance as great as themovement of the rod 10, but also the eect of the sharp blow of thefiring pin upon the plug 11 is to cause the closely wound spring 8 toexpand somewhat, so that the forward end of the spring 8 will moveforward a distance equal to the movement of the rod 10 plus theexpansion of spring 8. It is not necessary for the movement to be great.If the rod 10 moves forward one eighth of an inch the expansion of thespring might be one-sixteenth of an inch so that the needle will have atotal movement of three-sixteenths of an inch. rl`he distances abovegiven are merely for illustration, and I do not intend to be limitedthereby. Vhen the plug 11 is driven forward it compresses the spring 16which, after the hammer is cocked again, so that the ring pin may beretracted, will expand and carry the plug 11 back to the rear end of thetube 12, thereby also retracting the spring 8. The spring 8 hassufficient resiliency in itself to cushion the blow of the needle 9 andalso to recoil sufliciently to withdraw the needle 9 from the targetafter it is irst punctured before the firing pin 4 is moved back fromthe plug 11 to permit the plug and the rod 10 to move bach with therecoil of the spring 16.

The target 18 is attached to a target holder or block 21 which ismounted in such a way that if the gun is held with the muzzle againstthe target there will be a constant yielding pressure of the targetagainst the end of the gun such that it may yield to a forward push ofthe barrel of the gun but atthe same time will be maintained in contactwith the end of the barrel of the gun even while yielding to thepressure by the barrel.

The targets which are preferably to be used are paper targets 18 formedin series on a. strip of paper 22 so that when one target is used up, itmay be torn ofi:l of the strip and the strip drawn down into a positionto expose another target. The preferred method of arranging the targetstrip is to have it wound in the form of a roll 23 from which it can bereeled olf onto the front face of the target holder 21 as will now bemore particularly described. The roll 23 is journaled upon hangers 211which are suspended from the top of a box 25 which is hung upon hooks 61projecting from a suitable frame or fixed support 27. The target stripis threaded through a slit 28 in the target holder; thence is carrieddown over the front face of the target holder; thence back through theslot 30 and around again through the holder to the front over a roller29 journaled in the holder so that the target will be held taut. Thedistance between the slit 28 and the slot 30 is sufficient for theexposure of a single target sheet 18. lhen it is desired to pull downthe strip to remove the old target sheet and expose a new one, the strip22 can be pulled forward to unroll a suflicient length from the reel andthen by pulling down on the lower end it can be drawn down sufficientlyto expose the new target sheet upon the face of the holder. In orderthat the used up target sheet may be severed from the strip 1 provide atearing plate 55 hinged at 56 so that normally the tearing plate willhang down as shown in Fig. 8. The target strip runs down between thetearing plate and the target holder. The tearing plate can be turned upon its hinge to a position at right angles to the holder. Then it isdesired to tear off the target the strip is drawn out and pulled up toturn up the tearing plate to a horizontal position and then by a quicklateral turn the paper target can be torn on the edge of the plate.tearing plate is formed with teeth.

As already stated the target holder is hung in such manner as to exert aforward pressure against the muzzle of the gun. The manner of hangingthe target holder as shown in the drawings is as follows: Secured to theupper edge of the box 25 at opposite corners are two forwardly extendingbars or rails 31 which slope downwardly to their forward ends.Preferably these rails 31'are detachably connected with the box as forinstance being formed at their rear ends with downwardly extendingangle-hooks 32 which pass through staples or eyes 33 secured to thefront edge of the box, said angle-hooks having rearwardly extendinghorizontal portions 34 which are hemmed in on either side by studs 351so as to prevent swaying movement of the bars 31. The target holder 21is suspended from two carriages which are adapted t-o travelrespectively upon the two rails 31. Each carriage is constructed asfollows: The body of the carriage is in the form of a cross having thetwo lateral arms 35, 36, and the vertical downwardly extending portion37 and the vertical upwardly extending portion 38.

Preferably the The two lateral arms 35, 36 have their ends `reverselyturned forming ears 39 and 40 respectively between which and theirrespective arms 35, 36, are journaled the rollers 41, 42 which areadapted to bear against the under side of the rail 31 and the upwardlyextending portion 38 is reversely turned forming an ear 43 between whichand the upright portion 3S is journaled a roller 44 which is adapted toride upon the upper side of the rail 31, so that as the carriage travelsover the rail 31, the rollers 41 and 42 will engage the under sideof therail and the roller 44 will engage the upper side of the rail. The lowerend of the rail 31 is iattened out laterally as shown in Fig. 5 orotherwise formed with a stop which prevents the carriage from rollingoff the forward end of the rail. The lateral arms 35, 36 are twisted toflatten them to form spring necks 57, 58 so that the cross may have ayielding movement if a sudden unusual pressure is brought against thetarget holder, otherwise it might break if rigid. Gn the downwardlyextending leg 37 of each carriage is secured the target holder 21,)referably in a detachable manner. The means shown consists of a pin 46which passes through a hole in the leg 37 near the lower end thereof andenters a pin hole in the side of the target holder 2l. A staple 47inserted in the edge of the target holder above the pin 46 andprojecting slightly beyond the edge of the holder, forms a loop throughwhich the downwardly extending leg is passed before the pin 46 isinserted so as to form a guard or steadying means. Thus the targetholder can be readily attached to or detached from the two carriages. Onaccount of the downward incline of the rails 31 the carriages and thetarget holder carried thereby will be normally retained in the positionshown in Fig. 7 at the outermost end of the rails at some distance fromthe box 25.

Each target sheet 18 on the strip is formed with two bulls-eyes 5, c, inhorizontal alinement with each other together with concentric rings asusual in the case of targets, as shown in Figs. 5 and 9. A bulls-cye ais formed on the target holder in vertical alinement with the bulls-eyeb a short distance above the bulls-eye 6. The bulls eye a is stationaryon the face of the target holder, and it may be formed by marking thebullseye directly on the target holder in some contrasting color, as forinstance a black bulls-eye with a white or light colored back ground onthe holder. The target strip can be drawn down and adjusted so that thedistance between the bulls-eyevb and the bullseye a can be adjusted fora coarse, medium or fine sight.

Means are provided to insure the proper adjustment of the target stripwith relation to the bulls-eye a. The preferred means is to form eachtarget sheet with a horizontal line 53 and to form on the target holdera number of parallel horizontal guide lines 54 so located that thetarget strip may be pulled down to bring the line 53 into registrationwith any one of the guide lines 54 according to the kind of sight thatis being employed.

In order to provide for sighting at distant objects instead of at a spotconnected with the target, the target holder is formed with a fan-shapedslot 59 having in its lower end a rounded notch 52 and in this slot 59is fitted a removable section 6() on the lower end of which is formedthe bulls-eye a previously mentioned. This removable section 60 isfitted into the slot in such manner that when near sighting is desired,the removable section will be allowed to remain fitted into its positionin the target holder so that the marksman can sight at the bulls-eye aas previously described. When he desires to sight at a distant object,the removable section 60 will be removed and he will sight through thecurved notch 52 in the bottom of the slot. The back: wall of the box 25and the wall of the support 27 are each formed with a hole through whichthe marksman can see the distant object when sighting through the notch52. The removable section may be fitted to the slot 59 so closely thatfriction alone will retain it in position.

Attached to the side of the barrel is a marker 51 which, when the muzzleof the barrel is in contact with the target, will engage the target, andthe purpose of the bulls-eye c is to record the markings to indicate thedegree of wavering movement of the muzzle during the aiming. Thismarking mechanism which I have provided is as follows z-Clamped to thebarrel of the gun near the muzzle is a ring 48 to which is secured by aspring connection 49, a block or other suitable holder 50 carrying apencil or pin 51 which points forwardly in a line parallel with the axisof the needle 9. The forward end of the pencil 51 extends at least asfar forward as the forward end of the barrel and preferably a baretrifle beyond, so that when the end of the barrel rests against thetarget the pencil 51 will also be in rubbing contact with the target andwill describe lines upon the target corresponding with the waveringmovements of the end of the barrel. The distance between the centers ofthe bulls eyes 5 and o is equal to the distance between the axial lineof the point of the pencil and the axial line of the needle 9, so thatif the gun is sighted accurately with the eye in line with the bulls-eyea and the point of the needle 9 in alinement with the bulls-eye 5 thepoint of the pencil 51 will be in alinement with the center of thebulls-eye c and the wavering in the holding of a gun will be indicatedby `the pencil,

shown for instance by the irregular line cZ. This pencil may be anysuitable marking device which will leave a print or an impression for amark of any kind upon the target and in using the term pencil I meanthereby any suitable marking instrument. The pencil holder 50 is springseated, being shown as connected with the clamping ring 48 by a spring49 so that the pencil will have a yielding pressure upon the target. Thepencil 51 might normally project slightly farther forward than the endof the barrel so as to always insure a rubbing contact of the pencilwith the target, the spring yielding suiliciently so that the pencilwill be held under tension against the target when the muzzle end of thebarrel is pressed against the target.

When the marksman is practicing aiming he will sight through the foreand rear 'sights at the bulls-eye a., or through the notch 52 at thedistant object, holding the end of the muzzle against the target andwhen he thinks he has properly sighted the bulls-eye or distant objecthe will pull the trigger which will release the mechanism which actuatesthe firing bolt 3 driving forward the firing bolt to cause the firingpin to strike the plug 11 and to drive forward the spring 8 until theneedle 9 punctures the target sheet, the recoil causing the needle 9 towithdraw and then the gun is withdrawn from contact with the target andby inspection the marksman can see not only how nearly to the bulls-eyehe has punctured the target but also observes by the marking of thepencil with relation to the bulls-eye c how steadily he has held thegun.
